Method for filtering bad information, screen projector, electronic equipment and storage medium

The invention discloses a method for filtering bad information, a screen projector, electronic equipment and a storage medium. The method comprises the following steps: receiving original image information through a network channel; decoding the original image information to obtain video stream information; acquiring a picture frame from the video stream information, and inputting the picture frame into a pre-deployed bad information filtering model; performing information identification on the picture frame through the bad information filtering model; and outputting display image information based on the video stream information according to a result of the information identification. According to the method and the device, the screen projection equipment can have higher network flow bandwidth and lower system resource overhead so as to support high-resolution screen projection data transmission and display, and meanwhile, the bad information received by the embedded equipment in the screen projection proces
